I am getting a javascript error on a user control saying object referenced
is null. The situation is I have a left side user control that goes onto
every page. A user enters data and to do a search. The concept works well
enough but what is going on is when the page is in cache I click the go button
to perform the search and I get and error message in the __PostBack method
of the user control saying the object is not found. If the user control
is not cached the __Postback method works fine?

Any thoughts on this, I have the work around no cacheing but that is not
making good use of resources.
